Flashlights can be serious business for some people, with collectors spending upward of $200 for a high-end one. That's not what the Battery Snap is. This $5 flashlight connects directly to a 9V battery and can be turned on using a tiny switch on the top. That's it, there's nothing more to it. The simplicity of this gadget makes it great for kids, especially if you're giving them a physics lesson on electricity.

We reckon it's not exactly the newest product around. Let us know in TalkBack if you have one or have seen it in a novelty shop.
